Madison - We told you last week the state health department confirmed West Nile in birds in Oneida and Vilas Counties. Now it's confirmed the first human case of the virus.The case was confirmed in a Dane County resident. Last year, 57 cases of West Nile virus were reported among people in Wisconsin. That's the highest number of reported cases since surveillance began in the state. Most people never show symptoms. People who do become sick may have a fever, headache, rash, muscle and joint aches. Symptoms may begin three to 15 days after a bite from an infected mosquito. People with compromised immune systems and the elderly are at risk for complications to become serious.
